The energy you feel, an hour later

Why two foods with the same sugar can leave you steady or crashing — and how to read the difference.

Where your energy actually comes from — and why your body prefers carbohydrates over fat even when fat is available

The Krebs cycle is the engine at the centre of your metabolism. Understanding it explains why blood sugar spikes feel the way they do, why fat burning is slower, and what insulin is actually doing.

What your liver does in the two hours after you eat

The liver is not a passive filter. Every meal triggers a coordinated metabolic response that determines how much of what you ate becomes energy, how much becomes fat, and how much circulates in your blood.

What your liver does while you are not eating

Between meals and overnight, the liver switches from processing and storing to producing and releasing. This transition is one of the most important metabolic events that happens in your body — and most people never let it complete.

The second genome — what the gut microbiome is and why it matters more than we thought

Your gut contains roughly 100 trillion microorganisms encoding 150 times more genes than your own genome. They are not passengers — they are active participants in nearly every system in your body.

The gut-brain axis — how what you eat shapes how you feel, think and sleep

The gut and brain are in continuous two-way communication through the vagus nerve, the immune system, the bloodstream and a shared chemistry of neurotransmitters. Food is one of the most direct inputs into that conversation.

Not all protein is equal — essential amino acids, bioavailability and why the source matters

Tracking total protein grams tells you surprisingly little about whether your body can actually use what you ate. The quality of protein — its amino acid composition and digestibility — is the variable that determines the outcome.

When you eat matters — the circadian biology of meal timing and metabolic health

Your body handles the same meal very differently depending on when you eat it. Insulin sensitivity, fat oxidation, glucose tolerance and gut microbiome activity all follow a 24-hour rhythm that modern eating patterns routinely disrupt.

Inflammation is not a disease — it is a process. The problem begins when it never switches off

Acute inflammation is one of the body's most important healing tools. Chronic low-grade inflammation is a shared mechanism underlying cardiovascular disease, type 2 diabetes, Alzheimer's and cancer. Diet is one of the most direct variables in the difference between the two.

Magnesium — the mineral involved in 300 processes that half the population isn't getting enough of

Magnesium deficiency is one of the most common and most underdiagnosed nutritional inadequacies in the developed world. Standard blood tests miss it almost entirely. Its effects span sleep, anxiety, blood pressure, insulin sensitivity and energy production.

Sleep is not rest — it is the body's most active maintenance window

Growth hormone peaks, insulin sensitivity resets, the brain clears its waste, telomeres repair and the gut microbiome completes its daily cycle — all during sleep. Cutting it short doesn't save time. It borrows against every system that runs while you're asleep.

Hydration is not about drinking more water — it is about maintaining the right balance of fluids and electrolytes inside and outside your cells

The popular advice to drink eight glasses of water a day misses most of what actually determines whether your body is properly hydrated. Electrolyte balance, fluid distribution and the role of sodium, potassium and magnesium matter more than volume alone.

The liver's overnight shift — detoxification, repair and what it needs to run both

While you sleep, the liver runs its most complex chemical operation. Phase 1 and Phase 2 detoxification don't happen on a cleanse — they happen every night, and they depend on specific nutrients most people don't know to provide.

How the liver gets overloaded — and why non-alcoholic fatty liver disease is now the most common liver condition in the world

Non-alcoholic fatty liver disease affects roughly one in four people globally. It is driven primarily by diet, is silent for years, and is almost entirely reversible in its early stages — if you understand what is causing it.

Oxidative stress is not a wellness buzzword — it is a measurable imbalance with documented consequences

Reactive oxygen species are a normal product of metabolism. The problem begins when their production outpaces the body's ability to neutralise them — and diet is one of the most direct variables in that equation.

Cholesterol is not your enemy — your liver makes most of it regardless of what you eat

The relationship between dietary cholesterol, blood cholesterol and cardiovascular risk is far more nuanced than four decades of public health messaging suggested.

Your cells keep score — what telomeres and mitochondria reveal about how you age

Cellular aging isn't a fixed programme. It's a response to how much oxidative stress and inflammation your body accumulates over time — and both are shaped by what you eat.

Why your mouthwash may be undermining the vegetables you eat

The oral microbiome converts dietary nitrate into nitric oxide — a molecule that regulates blood pressure, insulin sensitivity and vascular health. Antibacterial mouthwash kills the bacteria that make this conversion possible.

Digestion begins in the mouth — and most people skip that step entirely

Overeating, inadequate chewing and eating too quickly each impair the body's ability to extract nutrients from food — through separate but compounding mechanisms.

Folate and folic acid are not the same thing — and where you live determines which one you're getting

One is found in food. The other is added by governments. Europe chose not to add it, and the consequences are measurable.

The lipolysis story

Why aged cheese feels so different physically

The real gut story with aged cheese

Short-chain FFAs like butyric acid are absorbed in the small intestine and used directly as fuel by colonocytes (colon cells) — they don't reach your microbiome intact, but they're bioactive

Vitamin A is not one thing

Two kinds of fiber — and why both matter differently

Fiber is not one thing. It's two distinct molecules with completely different jobs in the body.

The seed oil story — how industrialised fat became a health crisis

For decades, seed oils were positioned as heart-healthy alternatives to saturated fat. The chemistry told a different story.

The omega-3 to omega-6 ratio — the most important number nobody tracks

It's not the absolute amount of omega-3 that matters most. It's the ratio.

Magnesium — the mineral that runs the engine

Magnesium is a cofactor in over 300 enzymatic reactions. Without it, cells cannot produce energy efficiently.

Supplement timing — why when matters as much as what

Nutrient transporters are regulated by circadian clocks. The same supplement absorbed at different times of day delivers measurably different results.

Vitamin K1 and K2 — two vitamins sharing a name, doing completely different jobs

K1 handles blood clotting. K2 handles where calcium goes in the body. They are metabolically separate.

Glycine — the amino acid modern diets forgot

The body can synthesise glycine, so it's classified as non-essential. But synthesis covers only 3g per day. Metabolic demand is 10–15g. The gap is dietary.

CoQ10 — the spark plug of the mitochondria

Coenzyme Q10 sits at the heart of the electron transport chain — the final stage of ATP production. Without it, the chain stalls.

Choline — the essential nutrient nobody taught you about

Choline was only officially recognised as essential in 1998. Over 90% of people don't meet adequate intake. The richest source was demonised for 40 years.

The mitochondria are not just power plants

Mitochondria regulate inflammation, control cell death, produce steroid hormones, and signal to the nucleus. They are the first thing to show dysfunction — before any organ-level symptom appears.

Iodine and the thyroid — a gap hiding in plain sight

Iodine deficiency was solved in the West by iodised salt. Then processed food replaced home cooking and took the iodised salt with it.

Bile acids — the unspoken requirement for fat-soluble nutrition

Every fat-soluble vitamin and every carotenoid requires adequate bile output to be absorbed. Most people have never heard this.

The Body Is Not a Vessel — It Is the Condition

Modern culture inherited the idea that the mind is a passenger and the body its vehicle. Biology suggests the opposite.

What Alzheimer's Is Actually Telling Us

For decades, Alzheimer's research chased a protein. The energy hypothesis suggests we may have been looking at the wrong thing.

You Are What You Eat — But Not The Way You Were Told

The phrase was always right. The interpretation was always too shallow.

Phytic Acid — Why Grandmothers Soaked Their Grains

Every traditional food culture on Earth independently arrived at the same practice: soak, sprout, ferment, or cook plant foods before eating them. They didn't know the chemistry. They knew the outcome.

Lectins — The Kidney Bean Warning

Raw kidney beans contain enough lectin to put a person in hospital within hours. Properly cooked, the same bean is one of the safest, most nutritious foods on Earth.

Oxalates — Why Spinach's Calcium Doesn't Count

Spinach lists more calcium per gram than milk. Almost none of it reaches your bloodstream.

Tannins — The Iron Blocker in Your Teacup

A cup of tea with an iron-rich meal can cut the iron you actually absorb by more than half.

Solanine — The Green Potato Warning

A potato that's turned green under the skin isn't spoiled in the usual sense. It's making a toxin, in real time, in your kitchen.

Cooking Diminishes the Effect of Anti-Nutrients

Every plant on Earth would rather not be eaten. Cooking is the truce humans negotiated with the plant kingdom, long before anyone understood the chemistry behind it.
